-   *
-   * - A global, solitary "interaction lock" on a view.
-   * - If a node becomes the responder, it should convey visual feedback
-   *   immediately to indicate so, either by highlighting or moving accordingly.
-   * - To be the responder means, that touches are exclusively important to that
-   *   responder view, and no other view.
-   * - While touches are still occurring, the responder lock can be transferred to
-   *   a new view, but only to increasingly "higher" views (meaning ancestors of
-   *   the current responder).
-   *
-   * Responder being granted:
-   * ------------------------
-   *
-   * - Touch starts, moves, and scrolls can cause an ID to become the responder.
-   * - We capture/bubble `startShouldSetResponder`/`moveShouldSetResponder` to
-   *   the "appropriate place".
-   * - If nothing is currently the responder, the "appropriate place" is the
-   *   initiating event's `targetID`.
-   * - If something *is* already the responder, the "appropriate place" is the
-   *   first common ancestor of the event target and the current `responderInst`.
-   * - Some negotiation happens: See the timing diagram below.
-   * - Scrolled views automatically become responder. The reasoning is that a
-   *   platform scroll view that isn't built on top of the responder system has
-   *   began scrolling, and the active responder must now be notified that the
-   *   interaction is no longer locked to it - the system has taken over.
-   *
-   * - Responder being released:
-   *   As soon as no more touches that *started* inside of descendants of the
-   *   *current* responderInst, an `onResponderRelease` event is dispatched to the
-   *   current responder, and the responder lock is released.
-   *
-   * TODO:
-   * - on "end", a callback hook for `onResponderEndShouldRemainResponder` that
-   *   determines if the responder lock should remain.

-  /**
-   * A note about event ordering in the `EventPluginRegistry`.
-   *
-   * Suppose plugins are injected in the following order:
-   *
-   * `[R, S, C]`
-   *
-   * To help illustrate the example, assume `S` is `SimpleEventPlugin` (for
-   * `onClick` etc) and `R` is `ResponderEventPlugin`.
-   *
-   * "Deferred-Dispatched Events":
-   *
-   * - The current event plugin system will traverse the list of injected plugins,
-   *   in order, and extract events by collecting the plugin's return value of
-   *   `extractEvents()`.
-   * - These events that are returned from `extractEvents` are "deferred
-   *   dispatched events".
-   * - When returned from `extractEvents`, deferred-dispatched events contain an
-   *   "accumulation" of deferred dispatches.
-   * - These deferred dispatches are accumulated/collected before they are
-   *   returned, but processed at a later time by the `EventPluginRegistry` (hence the
-   *   name deferred).
-   *
-   * In the process of returning their deferred-dispatched events, event plugins
-   * themselves can dispatch events on-demand without returning them from
-   * `extractEvents`. Plugins might want to do this, so that they can use event
-   * dispatching as a tool that helps them decide which events should be extracted
-   * in the first place.
-   *
-   * "On-Demand-Dispatched Events":
-   *
-   * - On-demand-dispatched events are not returned from `extractEvents`.
-   * - On-demand-dispatched events are dispatched during the process of returning
-   *   the deferred-dispatched events.
-   * - They should not have side effects.
-   * - They should be avoided, and/or eventually be replaced with another
-   *   abstraction that allows event plugins to perform multiple "rounds" of event
-   *   extraction.
-   *
-   * Therefore, the sequence of event dispatches becomes:
-   *
-   * - `R`s on-demand events (if any)   (dispatched by `R` on-demand)
-   * - `S`s on-demand events (if any)   (dispatched by `S` on-demand)
-   * - `C`s on-demand events (if any)   (dispatched by `C` on-demand)
-   * - `R`s extracted events (if any)   (dispatched by `EventPluginRegistry`)
-   * - `S`s extracted events (if any)   (dispatched by `EventPluginRegistry`)
-   * - `C`s extracted events (if any)   (dispatched by `EventPluginRegistry`)
-   *
-   * In the case of `ResponderEventPlugin`: If the `startShouldSetResponder`
-   * on-demand dispatch returns `true` (and some other details are satisfied) the
-   * `onResponderGrant` deferred dispatched event is returned from
-   * `extractEvents`. The sequence of dispatch executions in this case
-   * will appear as follows:
-   *
-   * - `startShouldSetResponder` (`ResponderEventPlugin` dispatches on-demand)
-   * - `touchStartCapture`       (`EventPluginRegistry` dispatches as usual)
-   * - `touchStart`              (`EventPluginRegistry` dispatches as usual)
-   * - `responderGrant/Reject`   (`EventPluginRegistry` dispatches as usual)
